General relativity vs. Special relativity

General relativity vs. special relativity

Before we get in to details first we must know that understanding General relativity or Special relativity is easy and it would be better if we don't talk about the mathematical part of the 2 theories because some people wouldn't understand it

General relativity

Albert Einstein built up his theory of gravity, general relativity, through a series of 'thought experiments' and mathematical proofs. In 1915 he showed that gravity is caused by objects with mass such as planets and stars warping space-time. For example, the Earth is caught in the curve in space-time caused by the Sun, and the Moon is caught in a warp created by the Earth. Similarly light is bent when it passes massive objects like galaxies.

As strange as these ideas may seem, numerous observations have matched Einstein's predictions. and also General relativity says that in any frame of reference, a body can not exceed the speed of light, if a body is traveling at a speed near to the speed of light and try to cross it then its time will slow down which will lead to slowdown of its velocity, and the universal law persists. here comes the famous equation of Albert Einstein of E= mc^2. This formula says that is a body travels at a speed of light then its mass will change into energy and hence it cannot cross the speed limit. (At least not in these dimensions). On the other hand

Special relativity 

 special relativity is all about  situation when the speed of body exceeds the speed of light or when the speed is equal the speed of light or approaches the speed of light  then ; Time dilation came from here, mass inconsistency was from here, and everything is variable is from here. The theory says that if an object travels at a speed more then of light then it time would run slower then the rest of the universe and it s every thing would very by a factor of as shown in the  image and also says that laws of physics are the same in all inertial frames of references and the speed of light is constant relative to any observer
